Every time I accidentally say "Siri play ${song_name}" without appending "on Spotify" and Siri nonchalantly replies that it cannot find ${song_name} in my Apple Music library, I double down on my determination not to let them win!
Wasn't the default app thing declared a problem decades ago when Microsoft made you use IE? Why is Apple still allowed to force me to have Apple Music (and Apple Maps) as my defaults?
